What is this rock doing?

Asked by blueberry_kid (5864points) June 26th, 2014 from iPhone

So, I was in Guatemala for two weeks on a mission trip, and on the trip we all hiked up Pacaya Volcano.

It had erupted about three months ago. But, once we got to the top, we roasted marshmallows at the hotspots where all the lava rocks were. I decided to take a couple home with me but have no idea what’s happening.

They’re starting to crystallize or something and I’m really confused what’s happening.

At first they were red, but now they’re black and crystaly and I just want to know what’s happening.

Can the science side of fluther tell me what’s happening to the rocks?

They are oxidizing.

Agreed, with @ARE_you_kidding_me. They are oxidizing. Reacting with the oxygen in the air.

I love volcanoes…I am so jealous of you getting to do this!

The Guatemalan sister of Madame Pele is awakening. Known as Masaya, she is a hideous old woman and required victims thrown into volcanic craters.

To quibble ‘just enough’ with what you said, @yankeetooter, I think that you are in reality “envious” of @blueberry_kid‘s experience at a particular site and because of your love of vulcanism in general. If you were actually “jealous” of @blueberry_kid‘s adventure on a specific volcano, then we might question the relationship that you have with that volcano, or volcanoes in general, and wonder whether it is a healthy one for you… and for the volcanoes.

On the other hand, we could also question @blueberry_kid‘s relationship with volcanoes, but I don’t think there’s any call for that at this time.
